Specification of Letters Patent.

Patented Oct. 19,1920.

Application filed December 11, 1917, Serial No. 206,670. Renewed March 8, 1920. Serial No. 364,272.

To all 107mm it may concern:

Be it known that I ERASTUS P. MARSH, a citizen of the United States, residing at Chicago, in the county of Cook and State o'tlllinois, have invented certain new and useful Improvements in Atomizers, of which the following is a specification.

This invention relates to an atomizer attachment for use in connection with mechanism requiring internal lubrication and is more especially adapted for steam engines, and has for its principal object to provide an arrangement of this character that will be very eflicient and economical in practical use and cause a large saving in oil and other lubricating substances.

Another object is to provide a device that will afford a large atomizing or evaporatingsurface within a compact space and readily permit of the device being connected or disconnected with the greatest facility.

Another object is to provide a device that may be inserted in a steam circulating connection and feed the lubricant against steam or other nuid pressure.

VJith this and other objects in view, reference is had to the accompanying drawing in which- Figure 1 is an elevation and part section of a device embodying the improved fea tures.

Figs. 2 and 3 are detached details of construction. I

A may represent a broken away section of a steam pipe forming the usual connection between a boiler and engine; the upper end 4 connecting with the boiler, and the op posite end 5 connecting with the engine.

B represents a receptacle,- whichin this instance is 01. a cylindrical form and made of any suitable dimensions required in practical working. This receptacle may be .attached to the steam conducting pipe at any point between the boiler and engine. The respective ends of this receptacle are closed by the caps 6 and 7. The lower end of a pipe 8 is inserted in the upper end or" receptacle B and opens into the chamber 9 there in, as shown in the drawing. The upper broken away end of pipe 8 will have a proper connection with the reservoir. (not shown) from which the oil or other lubricant is fed into the atomizing receptacle B. The outer end of a steam tube 10 connects with the oil supply pipe 8; the opposite end and force it through the atomizer receptacle and thereby maintain a pressure above the normal or the steam pressure and insure a continuous circulation of the lubricant to the point to be lubricated.

A shut off valve 12 is inserted in tube 10 and provides means for closing the steam passage at this point.

A tube 14 is inserted in the lower endof receptacle B and connects with a feed-tube 15, the inner end of which eXtends into the steam pipe and terminates in the down turned out out end 16, as shown in the lower part of Fig. 1 and the detail Fig. 3. This terminal end presents the rounded surface 17 against the in coming flow oi": steam at this point and relieves the pressure on the discharge end of the feed pipe so that the oil or other lubricant atomized in the receptacle B will pass into the steam pipe and mingle with the steam on its way to the engine or other part to be lubricated.

A cut out valve 18 provides means for shutting off the steam when necessary for any purpose whatsoever and operates in conjunction with the shut off valve 12. The union joint 19 provides means in connection with the upper companion union 13 whereby the receptacle-B may be readily removed for repairs or other purposes without closing thethrottle valve or stopping the machinery.

In this instance the atomizer is filled with balls C and D to increase the atomizing surface and keep it within a compact space. These balls may be of a different diameter, the larger balls C and the smaller balls D in order to fill in more compactly and utilize all the space. These balls also act as a retarding agent and will regulate and equalize the flow of the steam and cause a uniform teed under any varying conditions. These balls will also have, in a measure, a cleansing and purifying effect in removing impurities and other foreign substances from the oil or other lubricant.

It is obvious that any other kind of filling may be used in the atomizer instead of the balls shown.

The atomizer is provided in its upper and lower ends with perforated diaphragms 20 and 21 which serve to check too rapid a feed and will strain out the larger impurities that may be in the oil. These diaphragms may be perforated plates or wire gauze as best adapted for the purpose.

The petcock 22 will provide means for drawing ofl" waste matter and other sediment. It will also provide means that will indicate whether a continuous circulation is being maintained through the atomizer receptacle.

It is obvious that I do not limit myself to the precise construction and arrangement shown, but may make such changes as practical working may require without departing from the intent and spirit of my invention.

Having thus described my invention, what I claim is 1. In a device of the class described, a receptacle connected with the source of lubricant supply and containing a number of balls or spheres held loosely therein, and means for maintaining a. continuous circulation therethrough under steam pressure.

2. In a device of the class described, a receptacle having a connection with the source or" lubricant supply, a filler-body of balls loosely inserted therein, and inlet and outlet connections through which an operative circulation is maintained under steam pressure.

8. In a device of the class described, a closed receptacle connecting with the source of lubricant supply, a filler-body of balls of different sizes held loosely therein, and the operative connections, through which a continuous circulation is produced under steam pressure.

4. In a device of the class described, a closed receptacle connected with the source of lubricant supply, a number of-balls of different diameters and irregularly disposed in said receptacle, and inlet and outlet connections through which a continuous circulation is produced under liquid pressure.

5. In a device of the class described, a

closed receptacle connected with the source of lubricant supply, a number of balls of different sizes held loosely therein, whereby the area o f the atomizing surface is greatly increased and the circulation therethrough somewhat retarded, the inlet and outlet connections, and means, as steam under pressure, for producing a continuous operation.

6. In a device of the class described, a closed receptacle connected with the source of lubricant supply, means contained in said receptacle for increasing the area of the atomizing surface and at the same time slow the circulation therethrough, inlet and outlet connections, and means carried thereby for maintaining an operative and continuous circulation under steam pressure.

7. In a device of the class described, an

'atomizing receptacle located between the source of the oil supply and the parts to be lubricated under steam pressure, balls of different sizes filling said receptacle, and the steam inlet and outlet connections provided with means for insuring a continu ous circulation of the combined lubricant and steam therethrough.

8. In a device of the class described, an atomizing receptacle, a steam pipe, an inlet connection having its open inner end extending into said pipe and cut-away on its upper side and an outlet connection extending into said pipe and cut-away on the underside whereby a continuous circulation is maintained through said receptacle.

9. In a device of the class described, an oil atomizing receptacle, a steam-pipe, an inlet connection extending into said pipe and stopping short therein and cut-away on the upper side to form a chute intake, and an outlet connection inserted in said pipe and extending into the steam space and cutaway on the underside in providing an overhang in hood end in guarding against back pressure.

In testimony whereof I atfix my signature in the presence of two witnesses.
